20.I met Mrs.Neidl in the ninth grade on a stage-design team for a play and she was one of the directors.Almost instantly I loved her.She had an Unpleasant voice and a direct way of speaking,(41)B she was encouraging and inspiring.For some reason,she was impressed with my work and me.

Mrs.Neidl's (48)B that year was,"Try it.We can always paint over it(49)D!"I began to take (50)D.I had been so afraid of failing but suddenly there was no failing--only things to be (51)Aupon.I learned to dip my brush into the paint and (52)C create something.

Being on that stage-design team(55)A  Mrs.Neidl changed me completely.Not only was I stronger and more competent than I had thought,but I also (56)Ba strong interest and a world I hadn't known existed.She taught me not to (57)B what people think I should do:She taught me to take chances and not be (58)D.Mrs.Neidl was my comforter when I was upset.Her  (59)Ain me has inspired me to do things that I never imagined (60)C.

解答 41-45BACDA   46-50DCBDD    51-55 ACBCA   56-60BBDAC
41.B 考察連詞及句子理解.前面unpleasant voice 和 direct way of speaking是消極意向,后面encouraging 和 inspiring是積極意向,因此需填轉(zhuǎn)折連詞,四個(gè)選項(xiàng)中and表并列,so表結(jié)果,for表原因,只有B選項(xiàng)yet表轉(zhuǎn)折.
42.A 考察名詞及篇章理解.第二段第二句話"She wanted to know how I thought we shouldthings",句意:她想知道我認(rèn)為我們?cè)撛鯓犹幚硎虑椋苯犹崾玖诉@個(gè)空應(yīng)該選觀點(diǎn)opinion這個(gè)詞.第二段倒數(shù)第四句話中也出現(xiàn)了這個(gè)詞從而驗(yàn)證了其正確性. B.impression 印象、C.information 信息、D.intention 意圖均不符合題意.
43.C 考察動(dòng)詞及篇章理解.根據(jù)文章主線選擇"處理"事情.考綱要求考生掌握handle 的兩種意思,名詞是"柄、把",動(dòng)詞是"處理",這里考察后者.A,make 做、創(chuàng)造 B keep 保持 D change改變 均不符題意.
44.D 考察代詞及句子理解.開始我不知如何回答是因?yàn)槲覍?duì)舞臺(tái)設(shè)計(jì)"一無所知". know nothing about sth 對(duì)某事一無所知.
45.A 考察名詞及篇章理解.解題關(guān)鍵詞是本句的"respond 回答、響應(yīng)",線索是第二段第一句中的"ask 提問"及第四句中的"answer 回答",因此這里填"question 問題"這個(gè)詞.B comment和Dremark選項(xiàng)是評(píng)論,C explanation是解釋,不符題意.
46.D 考察動(dòng)詞及篇章理解.本句的them指代opinions.form opinion形成觀點(diǎn).hold opinion持有某種觀點(diǎn),form 是個(gè)變化的狀態(tài),hold是個(gè)持續(xù)的狀態(tài),根據(jù)文意推斷作者開始并沒有觀點(diǎn),由于她相信我有觀點(diǎn)所以我形成了觀點(diǎn),強(qiáng)調(diào)形成這個(gè)過程,另外Begin to后接有變化感的詞,故選form不選hold.B.follow 遵照,C.evaluate評(píng)估與題意差別較大.
47.C 考察形容詞及句子理解.解題線索在后半句"so I began to show up to paint more and more"作者做的事情變多是Mrs.Neidl信任的結(jié)果,說明我是個(gè)可信賴(reliable)的人,C選項(xiàng)符合題意.其他三個(gè)選項(xiàng)happy 高興的 lively活潑的和 punctual準(zhǔn)時(shí)的都不能表達(dá)出這種合理的因果關(guān)系.另外迷惑性較大的lively通常用來形容物.
48.B 考察名詞及句子理解.引號(hào)里是一句鼓勵(lì)性質(zhì)的話,而且前面"that year"也是線索,說明這話是她的motto座右銘.迷惑性較大的C選項(xiàng)saying是諺語的意思,往往是人們長期形成的對(duì)生活及經(jīng)驗(yàn)的總結(jié),強(qiáng)調(diào)群體性及時(shí)間性,故不合適,message 信息,suggestion 建議,不合題意.
49.D 考察副詞及篇章理解.本題難度較大,解題關(guān)鍵詞是介詞"over",表覆蓋.選擇later 可以理解為"如果沒有畫好,稍后可以再畫一次覆蓋在之前的畫上."more更多,Instead 代替,不合題意.迷惑性最大的是again.表示"再一次、又一次"但是放在這里與over意思重復(fù),paint over it later相當(dāng)于 paint it again,故不選A.
50.D 考察名詞及篇章理解.take risks 固定搭配,冒險(xiǎn).通讀全文發(fā)現(xiàn)作者是開始很不自信,第四段開頭也提示了作者"shy","quiet",因此動(dòng)筆畫畫對(duì)他來說是個(gè)冒險(xiǎn),是自我突破的過程,文章最后一段也提到了take chances冒險(xiǎn),因此選D.take steps是采取措施、步驟的意思,與文章主題不搭,control 和 charge 都有控制的意思,不合題意.
51.A 考察動(dòng)詞及句子理解.Improve upon 改進(jìn).線索是本段開頭的座右銘"試試吧,我們永遠(yuǎn)可以重畫一次."因此不存在失敗,只存在改進(jìn).a(chǎn)ct upon按照、對(duì)…起作用,look upon 看待、考慮,reflect upon  考慮、回顧,均不符題意.
52.C 考察副詞及篇章理解.本段主要描寫了作者從不敢做到敢做的過程,根據(jù)前文提示作者曾很不自信,后來在 Mrs.Neidl的鼓勵(lì)下自信地拿起了畫筆,因此選confidently.A easily 容易的.作者超越自我的過程并不容易.B carefully 小心地.創(chuàng)作并不是個(gè)小心翼翼的過程.D Proudly 驕傲地.文章中沒有任何體現(xiàn).
53.B 考察動(dòng)詞.be recognized as"被公認(rèn)為、被承認(rèn)". introduce 介紹、引入,be identified as"被確定是",有驗(yàn)證身份的意思,be considered as"被認(rèn)為、被當(dāng)作".其中 be recognize as 有"被大家承認(rèn)、被普遍接受"的意思,表意更準(zhǔn)確.
54.C 考察動(dòng)詞.解題關(guān)鍵詞是"want".作者意識(shí)到自己想要的是什么,所以用realized.迷惑項(xiàng)是decided 決定.可以說決定要什么,但不可以說決定想什么,因?yàn)橄敕ㄊ遣豢煽刂频模甤onfirm 證實(shí) acknowledge 承認(rèn),與題意差別較大.
55.A 考察介詞.being with sb 與某人在一起.這里不能選of是因?yàn)槿牡谝痪湓,Mrs.Neidl是"one of the directors",所以不能說是她的團(tuán)隊(duì).below 和 by 搭配錯(cuò)誤.
56.B 考察動(dòng)詞.發(fā)現(xiàn)了一項(xiàng)愛好和一個(gè)未知的世界,選discovered.迷惑項(xiàng)是developed,這個(gè)詞可以與interest 連用表示形成了某種愛好,但是不可以與world連用表示"形成一個(gè)未知世界,"故排除.Take interest 取利,foster 培養(yǎng),均不合適.
57.B 考察動(dòng)詞及篇章理解."她教會(huì)我不要去在乎別人認(rèn)為我該怎么做",care 在乎,符合文意.a(chǎn)ccept 接受,judge 判斷,wonder 懷疑 均不合文意.
58.D 考察形容詞及句意理解.be afraid害怕.前面說take chance 冒險(xiǎn),后面理所當(dāng)然說不要怕(失。仪拔姆磸(fù)出現(xiàn)了afraid 這個(gè)詞,是全篇的關(guān)鍵詞.bored 無聊的,lazy 懶惰的,sad 傷心的,在文中均無體現(xiàn).
59.A 考察名詞及篇章理解.trust 信任.通讀全文會(huì)發(fā)現(xiàn)文中多次提到Mrs.Neidl對(duì)作者的信任,并在第三段明確使用了trust這個(gè)詞,因此推斷出答案.patience 耐心,curiosity好奇心,interest興趣,文中均無體現(xiàn).
60.C 考察形容詞及篇章理解."她對(duì)我的信任激勵(lì)我完成以前認(rèn)為不可能的事情","never imagined possible"等于"imagined impossible."認(rèn)為不可能的,貼合文意.a(chǎn)ccessible 容易取得的 enjoyable 有趣的 favorable 有利的贊同的 均不合文意.

點(diǎn)評(píng) 非等距離挖空的命題方式是完形填空的最大特色.短文首句不挖空,以便為考生理解全文留下足夠信息,命題者根據(jù)考查目的進(jìn)行挖空,造成信息鏈中斷,這就要求考生依據(jù)上下文的文意捕捉到空白處的缺詞.從近幾年高考完形填空題看,純語法知識(shí)幾乎不考,主要考查考生靈活運(yùn)用所學(xué)詞匯的能力,尤其是以考查實(shí)詞或信息詞為主,著重考查考生對(duì)文章的內(nèi)在邏輯和整體把握能力.因此,把握句間和段落之間的內(nèi)在邏輯關(guān)系,通過上下文暗示,對(duì)篇章、段落或句意的整體把握;再則,干擾項(xiàng)的設(shè)置與語法結(jié)構(gòu)無甚關(guān)系,重在文意干擾.因此,把握文意和具體語境,通過對(duì)詞義的辨析,是解完形填空的最好手段.

10.What's your opinion on spicy food?Some people cannot handle even the smallest amount of chili(辣椒) in their dinner while others can't get enough of it.
Scientists have long been puzzled by why some people love chili and others loathe it.Plenty of research has been done on the subject,dating as far back as the 1970s.Previous results showed that a love of chili is related to childhood experiences,and cultural influences affect our taste buds,too.But the latest study has found that a person's love of spicy food may be linked to his or her personality more than anything else,CBC News reported.
"We have always assumed that liking drives intake---we eat what we like and we like what we eat.But no one h as actually directly bothered to connect these personality traits with intake of chili peppers,"said Professor John Hayes from Pennsylvania State University,who led the study.
But before you look at the study,you should first know that"spicy"is not a taste,unlike sour,sweet,bitter and salty.It is,in fact,a burning sensation that you feel on the surface of your tongue.This got scientists thinking that maybe a love of spicy food is brought about by people's longing for thrill,something they usually get from watching action movies or riding a roller coaster.
In the study,97 participants,both male and female,were asked to fill out questionnaires about certain traits of their personality,for example.Whether they like new experiences or tend to avoid risks.They were then given cu ps of water with capsaicin(辣椒素),the plant chemical that makes chili burn,mixed into them.
By comparing the answers to questionnaires and what participants said they felt about the spicy water.Researchers found that those who most tended to enjoy action movies or take risks were about six times more likely to enjoy the spicy water.
Interestingly,we used to believe that the reason some people can withstand spicy food is that their tongue have become less sensitive to it.However,this latest study has found otherwise.It's not that it doesn't burn as badly,it's that you actually learn to like the burn,"Hayes explained.
25.What's the meaning of the underlined word"loathe"in the second paragraph?A
A.dislike                              B.fear
C.put up with                          D.a(chǎn)dapt to
26.What did Professor John Hayes and his team discover from their study?C
A.what we eat actually helps to develop our personalities.
B.Males are more likely to enjoy spicy food than females.
C.Those trying to avoid risks tend to be less interested in spicy food.
D.People are wrong to treat spicy as a kind of taste rather than a feeling.
27.Why do some people like spicy food according to the recent study?B
A.Because their taste buds have become less sensitive.
B.Because they love the burning sensation.
C.Because they want to challenge themselves.
D.Because the more they try spicy food,the less it burns.
28.What's the main idea of the passage?B
A.What he or she likes to eat mainly decides on his or her personality.
B.That a person enjoys sp icy food depends largely on the personality.
C.His or her childhood experiences decide on his or her personality.
D.His or her cultural background decides on his or her personality.

11.My daughter and I collected the empty cans and bottles in our home this morning.We had 6full garbage bags later so I knew we would be spending a bit more of time at the recycling center.When we got there,a man and his kids were also doing the morning recycling and were using wo of the four machines to recycle their plastic and cans.Luckily,we were able to use the 2remaining machines.
Of course,there were others that came,but when they saw the two families with garbage bags full of recycled things,they quickly left.However,one woman came in with just 5cans and looked as if she was in a hurry.So I stopped what I was doing and let her in to recycle her cans.Of course,she was grateful,and it felt good to let her go ahead of me.But that was not the whole story.

It was great to give and then to get an act of kindness in turn.It was small,I didn't expect it,but it surely brightened up my day.

15.Optimism May Help People Live Longer
People who have an optimistic view on life are more likely to live longer,a US study said Wednesday.
The study,published in the American Journal of Epidemiology,analyzed data from 2004to 2012from 70,000women enrolled in the Nurses'Health Study,a long-running US study tracking women's health via surveys every two years.
The researchers looked at participants'levels of optimism and other factors that might play a role in how optimism may affect mortality risk,such as race,high blood pressure,diet,and physical activity.
It found the most optimistic women,or the top 25%,had a nearly 30 percent lower risk of dying from any of the diseases analyzed in the study compared with the least optimistic women,or the bottom 25%.
The most optimistic women had a 16 percent lower risk of dying from cancer;38 percent lower risk of dying from heart disease;39 percent lower risk of dying from stroke;38 percent lower risk of dying from respiratory disease;and 52 percent lower risk of dying from infection.
Previous studies have linked optimism with reduced risk of early death from cardiovascular(心腦血管的)problems,but this was the first to find a link between optimism and reduced risk from other major causes.
"While most medical and public health efforts today focus on reducing risk factors for diseases,evidence has been mounting that enhancing psychological resilience (彈性,復(fù)原力) may also make a difference,"said Eric Kim,research fellow at the Harvard T.H.Chan School of Public Health and co-lead author of the study.
"Our new findings suggest that we should make efforts to boost optimism,which has been shown to be associated with healthier behaviors and healthier ways of coping with life challenges."
The study also found that healthy behaviors only partially explain the link between optimism and reduced mortality risk.One other possibility is that higher optimism directly affects our biological systems,Kim said.
Co-lead author and postdoctoral research fellow Kaitlin Hagan said optimism can be varied with relatively uncomplicated and low-cost interventions (干預(yù)),even things as simple as having people write down and think about the best possible outcomes for various areas of their lives,such as careers or friendships.
"Encouraging use of these interventions could be an innovative way to enhance health in the future,"Hagan said.

63.According to the recent study,optimism canB.
A.help women live longer than men
B.enable people to stay healthy
C.cure people of high blood pressure
D.make woman stay young and nice
64.From the recent study,the optimistic womenB.
A.took the risk of dying from infection
B.were less likely to die from some disease
C.had a 39% lower risk of suffering from cancer
D.were less likely to suffer from low emotions
65.The underlined word"mounting"in paragraph 7might be best placed byA.
A.increasing     B.a(chǎn)ppearing       C.doubling     D.showing
66.Both Kim and Hagan believed thatC.
A.simple but high-cost interventions should be tried out
B.higher optimism indirectly influences our body
C.optimism should be encouraged and developed
D.optimism can help people meet all kinds of challenges.

5.One part of the world is still largely unexplored.It is the deep sea.Over the years,many people have explored under the sea.But the first deep-sea divers(潛水員) wanted to find sunken treasure.They weren't really interested in studying the creatures of life there.Only recently have they begun to learn some of the mysteries of the sea.
It's not easy to explore the deep sea.A diver must have a way of breathing underwater.He mus be able to protect himself from great pressure.The pressure of air is about 15 pounds or every square inch.But the pressure of water ii about 1,300 pounds on every square inch!
The first diving suits were made rubber.They had a metal helmet(頭盔) with windows in it.The shoes were made of lead and weighed twenty pounds each!These suits let divers go down a few hundred feet,but they were no good for exploring the very deep waters.With a metal diving suit,a diver could go down 700 feet.Metal suits were first used in the 1930s.
In 1927,a diver named William Beebe wanted to explore deeper than anyone had ever gone before.He was not interested in finding treasure.He wanted to study the creatures and plants of the sea.His friend invented a metal ball called the Bathysphere.It weighed more than 5,000 pounds,but in it Beebe went down 3,028 feet.He saw many things that had never been seen by humans before.

47.People who first explored the deep sea hoped toD.
A.learn about the animals and plants of the sea
B.solve some mysteries about the sea
C.search information which is useful for studying
D.discover precious things under the sea
48.According to the text,what make (s) deep-sea diving difficult?A
A.The pressure of water.
B.The temperature of water,
C.The dangerous sea creatures.
D.The heavy breathing equipment.
49.Compared with rubber diving suits,metal diving suitsC.
A.had windows in the metal helmet
B.weighed twenty more pounds
C.were good for exploring deeper waters
D.began to be used much earlier
50.What do we know about William Beebe from the text?A
A.He broke the diving record in his time.
B.He failed to find the treasure he wanted.
C.He met something terrible under the sea.
D.He was the first diver to explore the deep sea.

11.Scientists from the United States say they have found fish and other creatures living under key waters in Antarctica.They made the announcement after completing three months of research at the Ross Ice Shelf-the world's largest floating ice sheet.
The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise.Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb,Illinois.They just finished up their research on our southernmost continent.Money for the project came from America's National Science Foundation.
"We chose a study site where,in the first year,we went into the subglacial(冰川下的)lake and tried to understand the environment there,both ecologically and in terms of the ice dynamics about how the lake operates,and how the sediment(沉淀物)underneath the ice sheet operates,as well,because it's the water and the sediment underneath the ice that control how fast the ice is flowing into the ocean."says Ross Powell,who led the investigation.The team included scientists,engineers,machinery and other supplies across the ice from the main U.S.scientific base at McMurdo Station to the researcher's camp.The camp was near a subglacial lake,where an earlier study took place.
Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea level.
"What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere."
Among the new instruments built for the project was a powerful hot water drill.The researchers used the drill to dig down some 740 meters.They collected water,sediment and other material from the grounding zone.
Working around the clock before the deep hole refroze,they sent a video camera down to the 400-square-meter undersea area.
Reed Scherer says the video images they saw in the Command Center were a total surprise.
"It's a very mobile environment.The bottom is changing constantly.And so the things that we saw were all very mobile organisms,things that swim and some things that crawl.And obviously they are getting enough nutrition that they can thrive on.Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active."
This is the farthest south where fish have ever been seen.How did the creatures get here?What do they feed on?And what effect will the retreating ice have on them?
Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues.
"We know that the ice is melting there at the moment and so by opening up the cores once they get back,we hope to be able to understand what the ice was doing in the past,relative to what it is doing now.And because it is melting so fast or seems to be melting fast at the moment,we anticipate that there will be some differences that we'll see in the history of the ice sheet from the sediment cores,once we open them up."But Ross Powell says the work raises more questions than it answers.
29.Scientists conducted the three-month research at the Ross Ice Shelf with the intention ofD.
A.predicting how climate change influences rising sea level
B.finding out whether there are life forms existing deep under Antarctic ice
C.proving the speed of ice flowing into the ocean is controlled by water
D.discovering an explanation of the effect the melting ice has on sea level rise
30.What made the researchers surprised when they saw the video images?A
A.Researchers saw fish in the farthest south for the first time.
B.A video camera was able to work well under deep icy waters.
C.Sediment cores present differences in the history of the ice sheet.
D.The drill should dig down 740 meters to collect things.
31.From sediment cores taken from the grounding zone,scientists will probably knowD.
A.what the ice will do in the near future
B.the ice in the grounding zone is melting at the moment
C.some differences rarely exist in the history of the ice sheet
D.something about the creatures under icy water in Antarctica
32.What can be inferred from the passage?A
A.Scientists will conduct a follow-up study on the frozen continent.
B.No creatures once appeared or lived in icy water in Antarctica.
C.America's National Science Foundation is in complete charge of the research.
D.Researchers have found how the sediment underneath the ice sheet operates.
